I recently had a situation where I needed to call a program that was executed on a Linux server from a Windows server. My problem was that I needed to connect to a Linux server via SSH, run the program and wait for the output to show up on a shared drive. I was restricted to using free tools that did not require installation, ones that could be executed on the command line. The specific problem was that in my Windows script I could not get past the password prompt when I connected to the Linux server via SSH with PuTTY.
